as i have a leaking front fork seal i have ordered new seals and bushings etc and i am considering fitting some racetech springs better suited to weight etc, my question is related to fluid level, i know the stock level is 62mm but on racetech site it states 130mm, seems like way less fluid in fork, has anyone fitted these that can vouch for this number being correct?, on 06 1300

The extra air volume allows the fork to utilize the stiffer springs without the penalty of being too harsh. More air and less oil makes for a more progressive ramp up of compression resistance as the fork nears maximum compression. I would follow the directions first, then modify oil level in necessary to suit personal preference.

IN MY OPINION.

With help from some people here including @dduelin this was my experience, I followed the directions.

makes sense, i watched a you tube vid from old guy on a bike where he fitted racetechs but did stock oil level dimension, i just saw the wilbers video and they did 120mm so must be a reason, thanks for reply
